I am trying to make a listview for a forum page but for the row under trailing and under the row where forumdata.getnop and the other data cannot be displayed under the list tile how do I fix this? there is no error with the class as removing the sized box with height 19 will just make it have an overflow error.

On a quick view, From this section of code:

SizedBox(
        width: 300,
        height: 19,
        child: Row(children: [
          Container(
              child:
                  Padding(padding: EdgeInsets.only(bottom: 20), 
                  child: Row(

Height of the SizedBox is 19 and the padding above second Row is 20. Thus the bottom padding completely hide the row.

/// replace with this
